Subject: [PATCH tip/core/rcu 07/45] torture: Allow variations of "defconfig" to be specified

From: "Paul E. McKenney" <paulmck@...ux.vnet.ibm.com>

Some environments require some variation on "make defconfig" to initialize
the .config file.  This commit therefore adds a --defconfig argument to
allow this to be specified.  The default value is of course "defconfig".
